A unique concept
Key metallurgical features
Properties of Creusabro® 4800, 8000, Dual result from the
• In-service surface hardening effect up to +70 HB
combination of an optimum alloying content and specific heat
treatment procedures.
• Fine dispersion of hard micro-alloyed carbides
• Deep-hardening, whatever the plate thickness
The soft quenching rates used in the mill fabrication practice:
• High mechanical strength • develop a bainite-martensite mixed microstructure with retained austenite
• Tough and crack-resistant with special properties.
• stimulate a fine dispersion of hard micro-alloyed carbides, which enhance the
• Uniform properties and low residual stresses resistance to sliding abrasion
• Softening resistance up to 450°C • produce a uniform through-hardened plate and low level of residual stresses
within the plate.
A REACTIVE SURFACE
Creusabro® 4800, 8000, Dual strongly improve their
wear resistance in service by a surface hardening
effect up to +70 HB under the action of local plastic
deformations caused by impact with rocks or pressure
by the abrasive particles. This is known as TRIP–effect
(Transformation Induced Plasticity).
DEEP HARDENING
The soft quenching rates used in the mill fabrication
practice produce a uniform through-hardened plate
and low level of residual stresses within the plate.
HIGH TEMPERATURE RESISTANCE
The grades are suitable for continuous operating
temperatures up to 450°C. Specific chemical
composition and initial microstructure result in a high
resistance to softening compared to classical water
quenched steels, which lose their hardness above
220°C.

multiple benefits, including:
Correct materials selection offers the potential to translate into major savings in fabrication
and maintenance costs, increased payload and productivity, and enhanced machine
performance.
The minor initial cost difference in the base material is far outweighed by the direct costs of
part fabrication, consumables and labor for repairs/replacements, as well as the even higher
indirect costs such as inventory costs and production losses due to machine unavailability.
